0h = Enable wetting current auto-scaling (to 2mA) in continuous
mode for 10mA and 15mA settings upon switch closure for all inputs
enabled with CSI
1h = Disable wetting current auto-scaling (to 2mA) in continuous
mode for 10mA and 15mA settings upon switch closure for all inputs
enabled with CS
For detailed descriptions for the wetting current auto-scaling, refer to
section Wetting Current Auto-Scaling.
